Naomi Osaka's Pan Pacific Open Campaign Ends in First Round

Naomi Osaka, the No. 7 seed, was eliminated in the first round of the Pan Pacific Open by 18-year-old Mia Pohankova.

Osaka, playing in her home country of Japan, was defeated by the young Czech player on Thursday.

Pohankova, who was born in 2005, is currently ranked 107th in the world. Osaka, a former world No. 1, has struggled with injuries and form in recent times.

Osaka's loss comes as a surprise, as she was expected to perform well in front of her home crowd.

Pohankova, who has been making a name for herself in the tennis world, has now defeated a top-10 player for the first time in her career.

Osaka's next tournament is scheduled to be the China Open in Beijing, which begins on September 25th.
